I completely disagree with @ucme – Happy Birthday is simply a tune used to convey a group of people’s intent on wishing someone a Happy Birthday. The melody is simple, as are most children’s songs (well, it is for children primarily) and much like a prayer – it is repeated several times…in unison. Like a chant. This predates written language and is very important for social and cultural interaction. I vote Happy Birthday is one of the best songs of all time.

@flutherother & @janbb I had to go look, because I’d never heard of it. Scarier than the song (and that was bad enough) was seeing Jimmy Savile’s name splashed over the screen, since it was a Top of the Pops clip. Creeped me right out.
